## Overview

Provides 100W power attenuation and directional RF power measurement from 0.4 to 2.5 GHz. Uses N-type female connectors for RF input/output. Applications include forward and reflected power monitoring, signal source leveling, and load isolation in RF test setups. Convection cooled.

## Function

Provides precise 20 dB attenuation of RF signals up to 3 GHz with a continuous power rating of 100 Watts; bi-directional operation allows signal attenuation regardless of connection orientation. Used for reducing power levels, isolating components under test, harmonic signal analysis, and serving as comparison standards in RF test setups. Constructed with Type-N female connectors, fully shielded to prevent extraneous radiation, and designed for self-cooling without requiring external cooling plates. Suitable for broadband RF applications demanding stable, conservative power handling and robust mechanical design.

## Platform

Designed for integration in RF test benches and communication systems, this device operates within coaxial transmission lines supporting frequency ranges typically up to several GHz. It functions to provide precise bi-directional attenuation of RF signals, protecting sensitive equipment from overpowered signals while allowing forward and reverse signal measurement. The attenuator interfaces directly with standard RF connectors (e.g., N-type), suitable for laboratory use, field testing, and broadcast applications where controlled signal level adjustment is critical for accurate diagnostics and system calibration.

## Accessories

Input/output facilitated by two N-type female coaxial RF connectors. These threaded, medium-sized connectors support bi-directional 100W RF signal transmission, designed for robust, low-loss performance typically up to 18 GHz. No external chassis or power supply required.

## Interface

Bidirectional RF attenuator with Type-N female coaxial connectors on both ends; frequency range DC to 3 GHz; nominal attenuation 20 dB; power rating 100 Watts; fully shielded, self-cooling design requiring no external cooling.
